Where: Libya (27.6° N, 12.6° E: paleocoordinates 52.1° S, 38.5° E)
• coordinate estimated from map
• outcrop-level geographic resolution
When: Bi'r al Qasr Formation, Eifelian to Eifelian (393.3 - 382.7 Ma)
• Age range of formation is Eifelian to Givetian (ref. 8780). However, the bulk is Eifelian, and the Givetian age applies only to the uppermost beds. This sample is said to be from upper part of formation, but it's not clear from what authors say whether it is high enough up to be Givetian.
• bed-level stratigraphic resolution
Environment/lithology: marine; sandstone and silty claystone
